Dermatomyositis is a rare disease with inflammation. Common dermatomyositis symptoms include a distinctive rash of the skin, muscle weakness and inflammatory myopathy or inflamed muscles.
It can affect both adults and children. There’s no cure for this condition, but symptoms can be managed.
The exact cause of dermatomyositis isn’t known. However, it has many similarities to an autoimmune disease.
In most cases, the first symptom is a distinctive skin rash on the face, eyelids, chest, nail cuticle areas, knuckles, knees or elbows. The rash is patchy and usually a bluish-purple color.
